From lactation to malignancy: A comparison between healthy and cancerous breast gland at single‐cell resolution reveals new issues for tumorigenesis

FEBS Letters, EarlyView.
Single‐cell RNA sequencing reveals an opposite role of SLPI in basal tumors based on metastatic spread, along with shared activation of specific regulons in cancer cells and mature luminal lactocytes, as well as downregulation of MALAT1 and NEAT1 in the latter.

Restriction modification systems in archaea: A panoramic outlook

Heliyon
Restriction modification (RM) systems are one of the ubiquitous yet primitive defense responses employed by bacteria and archaea with the primary role of safeguarding themselves against invading bacteriophages.

Restriction and modification of deoxyarchaeosine (dG+)-containing phage 9 g DNA

Scientific Reports, 2017
E. coli phage 9 g contains the modified base deoxyarchaeosine (dG+) in its genome. The phage encodes its own primase, DNA ligase, DNA polymerase, and enzymes necessary to synthesize and incorporate dG+.

Description of a PCR-based technique for DNA splicing and mutagenesis by producing 5' overhangs with run through stop DNA synthesis utilizing Ara-C

BMC Biotechnology, 2005
Background Splicing of DNA molecules is an important task in molecular biology that facilitates cloning, mutagenesis and creation of chimeric genes. Mutagenesis and DNA splicing techniques exist, some requiring restriction enzymes, and others utilize ...

Characterization of the DNA of Canine Adenovirus by Restriction Enzyme Analysis

Intervirology, 1985
The DNA of canine adenovirus (canAV 1, strain Behring H.c.c. 269) was characterized in detail. The molecular weight of canAV DNA was (20.1 +/- 0.1) x 10(6) daltons as determined by contour length measurements, and 19.9 x 10(6) daltons as determined by restriction enzyme analysis.

Cancer cell death induced by the NAD antimetabolite Vacor discloses the antitumor potential of SARM1

FEBS Letters, EarlyView.
Vacor, a compound converted into the toxic metabolite Vacor adenine dinucleotide (VAD) by the nicotinamide salvage pathway enzymes NAMPT and NMNAT2, exhibits antitumor activity by inducing rapid and complete NAD depletion. We report that Vacor toxicity is limited to cell lines expressing high levels of SARM1, a NAD glycohydrolase.

Expression of functional recombinant human tissue transglutaminase (TG2) using the bac-to-bac baculovirus expression system [PDF]

, 2016
Purpose: Tissue transglutaminase (TG2) is a unique multifunctional enzyme. The enzyme possesses enzymatic activities such as transamidation/crosslinking and non-enzymatic functions such as cell migration and signal transduction.

Mapping the evolution of mitochondrial complex I through structural variation

FEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Investigation of DNA-protein Sequence-Specific Interactions with a ds-DNA Array

Molecules, 2005
The sequence specific recognitions between DNAs and proteins play important roles in many biological functions. The use of double-stranded DNA arrays (ds-DNA arrays) for studying sequence specific recognition between DNAs and proteins is a promising ...

Plasmodium falciparum gametogenesis essential protein 1 (GEP1) is a transmission‐blocking target

FEBS Letters, EarlyView.
This study shows Plasmodium falciparum GEP1 is vital for activating sexual stages of malarial parasites even independently of a mosquito factor. Knockout parasites completely fail gamete formation even when a phosphodiesterase inhibitor is added. Two single‐nucleotide polymorphisms (V241L and S263P) are found in 12%–20% of field samples.
